1. The formation of polyurethane foam needs to go through two stages of foaming and curing. From the beginning of the mixing of the black and white materials to the stop of the foam volume expansion, this process is called foaming. During the foaming process, the system releases a large amount of re

The spraying polyurea construction work should be carried out under the conditions that the construction environment temperature is greater than 5°C, the relative humidity is less than 85%, and the base surface temperature is 3°C greater than the dew point temperature.If the temperature of the const

The base structure design of molded polyurethane rigid foam should be based on the actual engineering structure type, and put forward specific technical requirements, base treatment methods and quality control measures. The base layer of the molded polyurethane rigid foam is a load-bearing masonry w

How to mix the ingredients of small polyurethane foam equipment?Water-based enamel paint (environmental friendly formula): It contains calcite powder, zinc white powder, light calcium carbonate, double fly powder, gray calcium powder, and is characterized in that it uses a mixed colloidal solution o

Polyurethane foaming machine is widely used in multi-mode continuous production of rigid and semi-rigid polyurethane products, such as: petrochemical equipment, directly buried pipelines, cold storage, water tanks, meters and other thermal insulation and sound insulation equipment craft products.Pro
